DUST-GUARD FOR LOCOMOTIVE-CAB- WINDOWS.

SPECIFICATION forming part of Letters Patent No. 458,939, datedSeptember 1, 1891.

Application filed October 17, 1890. Serial K06681490- (No model.)

To all whom it may concern/.-

Be it known that I, FRANK O. BOND, of Port Jervis, in the county ofOrange and State of New York, have invented a new and useful Improvementin Dust-Guards for Locomotive-Oab Windows, of which the following is aspecification.

My invention is an improvement in locomotive-cabs, and particularly inthe construction of the windows, so that the engineer and fireman willbe protected from cinders, storm, &c., in looking forward, and so thatthe protecting window will not become clouded from the variations intemperature between the outside air and the interior of the cab.

The invention consists in certain features of construction and novelcombinations of parts, as will be hereinafter described, and pointed outin the claims.

In the drawings, Figure l is a perspective view of a part of alocomotive-cab provided with myimprovements. Fig. 2 is a horizontalsection, and Fig. 3 is a partial side View.

In locomotive-cabs the heat causes the condensation of moisture upon thewindow-glass, resulting in the clouding of the glass or the formation offrost thereon, so that the e11- gineer and fireman can only see out byopening the windows. In winter this exposes them to the force of thewind and storm, while at all times they are exposed to the dust andcinders. By my invention I provide a protecting or guard window whichmay be readily adjusted into and out of position for use, may be rigidlysecured in either of such positions, and will in both of its positionsbe free from the influences of the heat in the cab, so that it willnotbecome frosted or clouded in use.

The cab A may in general respects be of ordinary construction, havingthe fixed forward windows B and the rear windows 0, the latter beingsupported to slide forward alongside the front windows.

In connection with the usual side windows 13 and C, I employ what, forconvenience of reference, I term the guard window D, which is supportedto turn when closed into the plane of the cab side or when opened out toa plane at right angles, or ap noximately so, to the said cab side,securing devices being arranged to hold the guard-door in both its openand closed positions. In the construction shown the guard-window has aframe (1, and is hinged at one edge I) to the cab side at the rear endof the fixed window B, so that when closed it will turn forward withinthe frame of the window B and rest flush with the side of the cab. Ahinge-like fastening E is pivoted at e to the guard-window and has ahinged plate, which in the closed posi tion of the window fits under acatch E and has an opening to receive a pin E when the window is open.\Vhen opened, the guardwindow turns at right angles to the side of thecab and bears directly against the front end of the arm-rest F at theside of the sliding window C. This arm-rest forms a firm support forholding the guard-window when opened, such window being held open bymeans of the parts E E, as before described, or othersuitable securingdevices.

In operation, if the guard window be opened, the engineer or fireman canat any time, by opening the sliding window C, look forward through theguard-window, being protected thereby from the wind, cinders, dust, &c.,and such guard-window, being so arranged that it is exposed on bothsides to the same temperature, will be kept free of frost or thecondensation of moisture, by which it is clouded.

By my invention it will be seen that the guard-window may be set openand secured in such position, so that when the slide-window is openedthe guard-window is ready for use. It will also be seen that theguard-window can be quickly applied to an ordinary locomotive-cab,requiring no change in the construction of the body of the cab or of itswindows. Furthermore, the device is simple in construction and operationand possesses no parts likely to get out of order.

Having thus described my invention, what I claim as new is-- 1. Thecombination, with the locomotive cab having catch E and the arm-rest F,having pin E of the hinged guard-window and the fastening E, pivoted ate to the guard-window and having a hinged plate arranged, when theWindow is closed, to fit in the catch E, edge to the cab side in advanceof the armand provided with an opening arranged to fit rest and arrangedto open at right angles to over the pin E when the Window is opened, thecab side and to bear when open against 15 Wherebysuch Window maybesecured in both the arm-rest, and securing devices by Which 5 its openand closed positions, allsubstantially the said guard-Window may be heldin both as and for the purposes set forth. its open and closedpositions, all substantially 2.
